While the other houseguests were sleeping, the pair were getting raunchy as the camera panned to Sarah's hand on Chad's manhood before the scene concluded.

The controversial romance between Sarah Harding and Chad Johnson becomes one of the most talked-about things of this year's "Celebrity Big Brother". In a newly-released clip, the couple was getting into a super steamy sex act as they shared a bed for the first time in the Sunday, August 20 episode of the British reality show.

The former Girls Aloud member was seen cuddling and passionately kissing the shirtless 30-year-old hunk under the cover. "It's no one else's business," said the 35-year-old singer, to which Chad responded, "This is hard."

While the other houseguests were sleeping, things between the pair were getting hot and heavy. "Can you feel that there? Yes that there?" "The Bachelorette" star whispered to the blonde beside him. They continued getting raunchier as the camera panned to Sarah's hand on Chad's manhood before the scene concluded.

"There's a lot of heavy petting going down between the couple," the insider revealed, adding that the show's producers had to edit the scenes to make it not too graphic for the broadcast. "Sarah's hand disappeared under the covers and Chad's boxers came off. Viewers can draw their own conclusions about what happens but it's pretty clear."

People have always been critical of the romance Sarah and Chad had after Sarah admitted that she had a boyfriend outside the famous Borehamwood mansion. The two, however, couldn't be more careless as they previously went off to the camera-less bathroom for a private make out session.
